Description

Sliding device for transmission of arbitrary continuous curve guide rail

Technical Field

The utility model relates to a slip table especially relates to a slider that is used for arbitrary continuous curve guide rail to transmit.

Background

At present, the curved guide rails on the market mostly adopt a combination form of a linear guide rail and an arc guide rail, fig. 1 is a schematic structural diagram of the curved guide rail in the prior art, and as shown in fig. 1, the curved guide rails are arranged in a closed rectangular shape, a snake shape, an L shape, a U shape or the like. The driving device basically drives the curve guide rail transmission device by using flexible or intermittent driving mechanisms such as a belt, a chain, a deflector rod and the like, and although the driving modes realize that the track sliding table can smoothly pass through a corner, in the field of high-positioning-precision control, due to the limitation of the structure, elasticity or impact exists, transmission speed fluctuation and delay occur, so that the transmission precision of a system is lost, and the requirements of high-precision positioning or real-time control of the position of the system cannot be met.

In the linear transmission process, if the sliding device needs to realize the requirement of high-precision positioning, basically, the short-distance transmission mechanism adopts a ball screw, and the long-distance transmission mechanism adopts a gear rack to drive. When the gear rack sliding device with the conventional configuration passes through a curve guide rail, the gear and the rack are separated or interfered, so that the gear and the rack cannot be normally meshed with the sliding device. According to the scheme, through analyzing the specific reasons that the gear and the rack at the turning position of the curve guide rail cannot be normally meshed, the transverse floating type gear and rack driving mechanism is arranged on the driving device, the sliding table walking on any continuous curve guide rail is realized, the driving gear and the rack on the sliding table can be normally meshed, and high-precision accurate positioning and real-time control can be carried out through the control system.

Fig. 2 is a schematic structural view of interference at a corner of a rack guide rail in the prior art, please refer to fig. 2, and in the related process of the conventional sliding table, when the sliding table 1 runs to the corner of a curved guide rail, a rack and a pinion interfere and cannot pass through the sliding table. This has led to a reluctance of engineers to use rack and pinion slides to travel on curved tracks. Experiments show that the driving gear G can not be normally meshed and driven due to interference or separation between the driving gear G and the curved rack caused by transverse deviation of the driving gear G relative to the curved rack at a turning position.

Therefore, the utility model provides a sliding device that overall arrangement is transmission of continuous curve guide rail can be used to various material and carry, automation equipment travel drive etc. especially is used in the occasion of high positioning accuracy drive control, like robot walking ground rail, and other have high accuracy transmission's equipment etc..
